334+ indicators from 6 authoritative international organizations
Statistics of the World sources its statistical data exclusively from official international organizations — we never fabricate or adjust values, and every number on this site can be traced back to its original publisher. This page documents all of our data sources: the six statistical organizations behind the country indicators, plus the market and event feeds that power our live-data tools.
1. IMF World Economic Outlook (WEO)
The IMF WEO is the gold standard for international macroeconomic data. It provides harmonized GDP, growth, inflation, unemployment, government debt, current account, and fiscal indicators for 193 countries, including estimates for the current year and projections 5 years forward.
Key indicators from IMF: GDP, GDP growth, GDP per capita, inflation, unemployment, government debt, GDP PPP.
2. World Bank World Development Indicators (WDI)
The WDI is the world's most comprehensive development database, covering 300+ indicators across health, education, environment, infrastructure, governance, trade, labor, demographics, and more. Data is compiled from national statistical agencies, UN agencies, and specialized organizations.
